Thanks. I want to go back and follow up, because I felt that I got cut off last time. Thanks for giving me a bit more time.
It sounded as though there are crucial decisions with impacts upon costs, timelines, configurations, space allocation and project management, for sure. I think you mentioned those in your briefing. The visitor welcome centre, the chamber, the gallery, the lobbies all have key decisions needing to be made. They would have a pretty big impact on the overall parameters of this project.
Size and scope, I think, are going to shift dramatically, depending, as you said, upon whether there are structural changes—that the chamber needs to be expanded, or something. That's a big decision that is going to impact upon everything else.
I guess I'm going back to what methods of engagement should be used and included in a process such as this to help make some of the key decisions. They really are key, to speak to the point made by my colleague from the Conservative Party, who was concerned about costs and cost overruns. Ensuring that we have a good process for engaging MPs in helping to make some of those decisions is probably going to help manage costs and expectations.
My really clear question, after this long preamble, is: what are the methods of engagement that should be used, and how often should MPs be given input, in an ideal scenario?
